Following code causes compilation error in dmd 2.055.

code:
-----
struct S
{
     disable this();
    this(int a) {}
}

S s = S(10);
writeln(s);
-----

output:
-----
/path/to/phobos/std/stdio.d(1483): Error: variable std.stdio.writeln(T...) if
(T.length == 0).writeln._args_field_0 initializer required for type S
/path/to/phobos/std/stdio.d(1495): Error: variable std.stdio.writeln(T...) if
(T.length == 1 && is(typeof(args[0]) : const(char)[])).writeln._args_field_0
initializer required for type S
/path/to/phobos/std/stdio.d(1508): Error: variable std.stdio.writeln(T...) if
(T.length > 1 || T.length == 1 && !is(typeof(args[0]) :
const(char)[])).writeln._args_field_0 initializer required for type S
-----

I think this is a regression.

This issue will be fixed by dmd/pull/286 as a side effect.
https://github.com/D-Programming-Language/dmd/pull/285

That patch applies STCparameter to function parameters correctly inside
template constraint, then errors are suppressed.
